Hey all! So this is my first post, so please take it easy Anyways, I am a 17 year old girl, and have been training seriously for about 7 months. The gym I go to unfortunately does not have a squat rack, so I found myself squatting in the smith machine for basically the past half year... which led to okay gains... but definitely not as good as a barbell's. Yesterday, I stepped it up and said to screw the smith machine. I racked a barbell off the bench press (Ghetto, I know lol), stepped out with it, and just squatted using benches as "safety racks." However, while I am squatting only my bodyweight here, I am afraid my squat has been turned into a "good morning" exercise. My hips drive up first, and I excessively lean on the ascent. One thing might be I'm not breathing properly. Another might be that I'm not driving my elbows down, nor pushing back into the bar when I ascend. Based on this video, what else do you all think I could possibly fix for this problem? Thank you so much!
